12 Claims.

This invention relates to ironing machines, and has to do with ironingmachines intended for domestic use and which employ a rotating roll anda cooperating shoe movable toward and away from the roll.

It is customary to dampen articles to be ironed preliminary to theironing operation. It frequently happens that such articles areconsiderably damper at certain portions thereof than at others. If thesearticles be passed through the ironing machine at a uniform rate, thereis the possibility that the damper portions of such articles will not bethoroughly dried during the ironing operation. It is an object of myinvention to provide simple and eilicient means under control of theoperator for momentarily stopping rotation of the article while the shoeis in contact with the article, so that the damper portions of thearticles being ironed may be subjected to the heat of the shoe, at thediscretion of the operator, for sufficient time to assure thoroughdrying thereof, such means being operable to cause again rotation of theroll while the shoe remains in opcrative relation to the same.

In the patent to Carl F. Anderson and Rudolph W. Janda, No. 1,656,656,dated January 17, 1928, for Ironing machine, there is disclosed anironing machine of the character above referred to and which is providedwith a box cover hinged to the bed structure of the machine and movableinto position to enclose the ironing roll and shoe, this cov-cr, whenopened, occupying a position alongside the hot shoe in parallel relationthereto and serving as a guard therefor. In the machine of the patentreferred to, means is provided for quickly releasing the shoe and movingit away from the roll, in case of emergency. This means includes arelease lever accessible from the front of the machine. A further objectof my invention is to provide a release lever of proper length to extendwell above the ironing shoe and roll so as to b3 readily grasped andoperated by the operator of the machine and without danger of theoperators arm coming in contact with the hit shce, this lever beingcapable of being disposed in a position below the shoe and roll so asnot to interfere with positioning over the latter of a box cover the topwall of which, When in closed p( sition, is adjacent the top of the rolland the shoe. A further advantage of the relatively long release leveris that it facilitates operation of the release mechanism with ease andexpedition. Further objects and advantages of my invention will appear'from the detailed description.

In general, the construction of the machine 25 of the instantapplication is similar to thatof the ironing machine disclosed in myPatent No. 1,867,839, dated July 19, 1932. The machine includes a bedplate I5 having a depending peripheral flange I6 to which are securedthe upper ends 30 of supporting legs I1 in a suitable manner, as by nutand bolt means, these legs being formed of sheet metal of suitable gageand of angle cross section. The legs I'I are disposed at the corners ofthe bed plate, which is of rectangular shape in 35 plan, and may, ifdesired, be provided at their lower ends with suitable casters such asare disclosed in my patent above identified. Likewise,

any suitable means may be provided, if desired, for bracing the legs andmaintaining them in 4o proper spaced relation.

Bed plate I5 is provided, adjacent one end thereof, with an openingwhich accommodates a main gear housing I8, the lower portion of thishousing iitting through the opening and extending below the plate.Housing I8 is provided with an outwardly extending ange I9, at the endsand the inner side thereof, this ange seating upon the upper face of bedplate I5 and being secured thereto in a suitable manner, as by means ofbolts 20 passing through the flange and the bed plate, nuts (not shown)being screwed onto these bolts. The outer side of the main gear housingis closed by a lower plate 2| suitably secured thereto, as by means ofscrews, and by an upper plate 22 suitably secured to 4the housing as bymeans of screws, one of which is shown at 23, this upper plate beingprovided, at its lower end, with an inwardly offset lip 24 which engagesover the upper edge portion of plate 2l.

A worm gear housing 25 is suitably secured, as by means of screws 26(Figure l), to the underface of housing I8. The housing 25 is providedwith a depending boss (Figure 2) 2,1 which is suitably bored from itsupper end for reception of a. shaft 28 rotatably mounted therein. Thisshaft extends upward through a bearing bushing 29 which fits through acollar 30 integral with and extending upward from bottom wall 3| ofhousing I8, this collar being concentric with the bore of boss 21. Aworm gear 32 is keyed or otherwise suitably secured upon shaft 28 and isrotatably seated upon the upper end of boss 21. Hub 33 of worm gear 32contacts a flange 34 at the lower end of bushing 29 and acts to holdthis bushing against downward movement.

rIhe upper portion of shaft 28 is of reduced and squared cross section,at 35 (Figure 4) and fits into a correspondingly shaped bore in a clutchmember 36 secured upon portion 35 of shaft 28 in a suitable maner, as bymeans of a set screw 31. The upper portion of the bore of clutch member36 is of enlarged and circular cross section and receives the lower endof the lower reduced and squared portion 38 of a shaft 39 rotatablymounted at its upper portion through a bushing 4D which extends througha relatively thick rib 4I projecting from front wall 42 of the gearhousing I8. A dog pointed screw 43 screws into the rib 4I, the point ofthis screw engaging into an annular groove 44 formed in the shaft 39 andholding the latter against endwise movement, this screw also passingthrough the bushing 40 and holding the latter in the rib 4I. Shaft 39 isdisposed coaxially with shaft 28 and the lower end of bushing 46contacts a cup washer 45 disposed about shaft 38. An expansion coilspring 46, mounted about shaft 39, is confined between washer 45 and anangle bearing ring 41 the lower fiange of which seats upon the upperface of a flange 48 at the lower end of a clutch member 49 slidablymounted upon squared portion 38 of shaft 39. Clutch member 49 tapersupward and is provided at its upper end with an annular shoulder 56,beneath which the other flange or arm of ring 41 engages, this ringfitting snugly about the body of the clutch member. The clutch members36 and 49 are of known type and are provided, at their adjacent ends,with teeth which cooperate to establish driving connection between thesemembers when they are in operative relation, in a known manner. The cupwasher 45 and the ring 41 permit of the use of a spring of ample sizefor the purpose intended, and the ring 41 is advantageous as reducingfriction and eliminating any tendency to binding of the clutch member 49on the squared portion 38 of shaft 39.

Spring 46 acts to urge the clutch member 49 downward into operativeengagement with the lower clutch member 36, thus establishing drivingconnection between the shafts 28 and 39. A bevel pinion 5Iy is suitablysecured, as by means of a pin 52, on the upper end of shaft 39, abovethe rib 4I. This pinion meshes with a bevel gear 53 suitably secured, asby means of a pin 54, upon the outer end of a roll drive shaft 55. Thisshaft 55 is rotatably mounted through a boss 56 extending from the innerface of wall 42 of gear housing t8, and through a boss 51 aligned withboss 56 and extending from the outer face of wall 42. Shaft 55 extendsthrough a tubular supporting arm 58 suitably secured, at its outer end,in boss 51. This arm 58 projects inward over bed plate I5 to within ashort distance of 5 the other end thereof,- and may contain suitableantifriction bearings for rotatably supporting shaft 55 in arm 58.

A worm shaft 59 is rotatably mounted in the worm gear housing 25, in asuitable manner, and 10 carries a worm 68 rigid therewith, this wormmeshing with the worm wheel 32. Shaft 59 extends beyond the inner sideof housing 25, beneath bed plate I5, and is connected by a suitablecoupling 6I to armature shaft 62 of an electric motor 15 63 supported bybrackets 64 suitablysecured to the bed plate. Suitable means is providedfor connecting the motor into an electric circuit.

Upon closing of the motor circuit, worm wheel 32 drives the shaft 28,the direction of drive of 20 the motor being such that this shaft isdriven in a clockwise direction when viewed from above. With the clutchmember 49 in its raised or inoperative position, shaft 28 and clutchmember 36 rotate without effecting rotation of shaft 39. 25 Lowering ofthe clutch member 36 serves to clutch shaft 39 to shaft 28, these twoshafts then becoming, in effect, a single shaft which serves to drivethe roll shaft 55 through the pinion 5I and bevel gear 53.- Shaft 39 isthus driven, at this 30 time, in a clockwise direction as considered inFigure '7.

Sleeve 58, in conjunction with shaft 55, provides means for rotatablysupporting a roll 65 comprising a sheet metal body 66 of cylindrical 35shape, and suitably arranged reenforcing rings disposed within this bodyand secured thereto in a suitable manner, as by box welding. One ofthese rings, designated 61, is disposed adjacent the open end of body 66and extends inward to 40 within a short distance of the end of sleeve58. 'I'he cylindrical body of the roll is adapted for reception of a.suitable length of fabric which may be secured thereon in a suitablemanner and is wrapped about the same to form a pad 68 com- 45 posed of aplurality of layers of the fabric, there being a suitable fabric cover69 disposed over the pad thus provided.

The end portion of shaft 65 remote from housing I8 is flattened at 16and fits through a corre- 50 sponding slot 1I in reenforcing ring 61.The flattened 'portion 10 of shaft 55 is threaded, and ring 61 isclamped between a nut 12 at the inner face of the ring and a cap nut 13at the outer face of the ring. The nut 12 abuts the outer 55 face of aball bearing structure 14 of known type, suitably mounted in the outerend of Ysleeve 58, and coacts with bevel gear 53 and boss 66 to holdshaft 55 against endwise movement, the two nuts 12 and 13 screwing ontothe end portion 10 of 60 shaft 55. The roll is thus mounted for rotationon the axis of arm 58 and when it is desired to remove the roll, thismay readily be accomplished by removing cap nut 13, after which the rollmay slide lengthwise off of the shaft 55 and arm 58, 55 away from thegear housing I8. To replace the roll, this operation is reversed.

An eccentric structure 15 is mounted for free turning movement about thebearing bushing 29. This structure is provided, at its underside, with70 a reduced eccentric element 16 which seats upon the upper face ofcollar 30. An eccentric strap 11 fits above eccentric element 16. Thisstrap is formed at one end of an arm 18 which is provided, at its otherend, with a fork 19. 'I'his fork 75 receives a block 88 pivotallysecured in the fork, on a vertical axis, by a. pin 8|. This block isalso pivotally secured, by apin 82, to the lower end of an arm 83secured upon and depending from a. shoe operating shaft 84 which isrockably mounted through a bearing sleeve 85 projecting from the innerwall of gear housing |8. This sleevey 4lng concentric with shaft 84.This provides a lost motion connection between arm 81 and shaft 84 whichpermits of limited rocking movement of the arm independently of theshaft.

A fork member 9| is pivotally connected at its lower end, by a headedpin 82, to the other end of arm 81. This fork member is provided witharms 83 which extend beneath the lower flange of angle ring 41. Adjacentits upper end, fork member 8| is provided with a vertical slot 84 whichreceives enlarged element 43a of screw 43, there being a washer 85confined between the head of this screw and the outer faceof member 8|.In this manner, the 'fork member is slidably mounted on rib 4| ofhousing |8 for vertical movement. The fork member 9| is furtherprovided, adjacent its upper end, with two lingers 96 disposed at eachside thereof and extending therefrom oppositely to the arms 93. A clutchshaft 91 is rockably mounted in housing 8 transversely thereof andadjacent fork member 9|. This shaft is flattened at 81a (Figure 3) andfits snugly through correspondingly shaped openings 98 (Figure 8) in thearms of a U-shaped cam member 98. Member 99 embraces fork member 9| andthe arms of member 99 are rounded to provide cam surfaces |88. The armsof member 99 are also provided with fingers |8| adjacent the upper endsof the cam surfaces |88 and disposed to contact the outer surface ofmember 8| when the latter member is in lowered position, as in Figlure8. In this position of member 9|, fingers 96 rest upon the upper edgesof the arms of member 99, which is horizontal position, and elements |8|contact member 9| adjacent the fingers 96. A suitable handle |82 issecured upon shaft 91, exterior of housing I8 and at the front wallthereof. With shaft 91 in the position illustrated in Figures 2 and 3,fork member 9| is in its lowered position and clutch member 48 islowered into engagement with clutch member 38 thus driving the roll 65in the manner previously described. By turning the shaft 91 in an arc of90 and in a clockwise direction, as viewed in Figure 3, cam surfaces |88of cam member 98 are caused to exert a camming action on fingers 86 soas to raise the fork structure 9| sufficiently to move clutch member 48upward into its inoperative position, in which it is out of engagementwith clutch member 36, thus stopping the roll 65. In this position ofthe cam member 89, the pressure exerted by spring 46 is transmitted tothe cam l member through fingers 96, the line of pressure beingsubstantially in the plane of the axis of shaft 91. This, in conjunctionwith the friction between the parts, serves to hold the clutch member449 in its raised position. Turning the shaft 91 in the oppositedirection serves to return the clutch member 49 to operative position soas to drive again the roll 65. In this manner,

the roll may be stopped and started at the will ofthe operator, bysuitable turning of handle |82.

Eccentric member 15 ls provided with an upwardly projecting flange |85concentric with 5 shaft 28, the upper face cf this member being flat orplane from the flange to the outer 'edge of the body portion thereof.Member 15 is provided,- in the upper face thereof and adjacent flange|85, with a channel |86 of appreciable l0 depth (Figure 5), whichreceives a ltension coil spring |81. One end of this spring is secured,by a pin |88, to member 15. At its other end, spring |86 is providedwith an eye |89 which receives a tongue ||8 pressed downward from a l5clutch operating ring which fits about flange |85 and seats upon theupper face of eccentric member 15, this ring forming a closure for theupper end of channel |86. An annular clutch yoke ||2 is disposed aboutflange |85 and seats 20 upon ring This yoke is provided withdiametrically disposed notches ||3 which receive angularly disposed tabs||4 formed integrally with the ring and projecting upward therefrom,these tabs being outwardly offset relative to the 25 body portion of thering. A star wheel ||5 is disposed within the pocket or recess definedby flange |85 and ts about the squared portion 35 of shaft 28. This starwheel and the yoke ||2 are preferably of laminated construction, the 30elements thereof being suitably secured together, as by riveting.However, the yoke and the star wheel may be otherwise constructed ifdesired. An annular cover plate |6 is disposed beneath clutch member 36and seats upon flange |85. to 35 which it is secured by screws |85a,this plate projecting outward beyond this flange and acting to hold theyoke ||2 and the star wheel ||5 and cooperating parts against upwardmovement.

Referring more particularly to Figure 4, flange 40 |85 is provided witha slot ||1 extending therethrough and of a size to accommodate a clutchdisc I8 of a size and shape to t into the notches H50. of the star wheel||5. Clutch yoke ||2 is provided, in its inner edge, with a recess ||2aof 45 proper depth to receive the portion of disc ||8 Which projectsbeyond flange |85 when this disc is in its outer or inoperativeposition. This recess is provided with an extension ||2b of reduceddepth to accommodate the outer portion 50 of the disc ||8 when thelatter is in its inner or operative positon. The spring |81 urges ringin a clockwise direction, as considered in Figure 4.

A trip finger ||9 is roekably` mounted upon a boss |28 projecting inwardfrom the front wall 5" of gear housing I8. A control rod |2| is slidablymounted in the top of housing I8 and is pivotally connected at its lowerend to finger ||8. A button |22 is suitably secured upon the upper endof this rod, and an expansion coil spring |23 is GO mounted about therod |2| and confined between this button and the bottom of a bore |24provided in housing |8 to accommodate the button. Spring |23 servesnormally to hold the rod I2| raised, thus normally holding the outer endof 6* trip nger I9 depressed and in contact with the upper surface ofcam member l5. The nger, when in its normal operative position, isdisposed to contact tabs ||4 of the ring This serves to hold the yoke||2 in such position that recess 70 |2a thereof is in allgnment withslot ||1, due to contact of tabs ||4 with the end walls of notches ||3.At this time the disc ||8 is in its outer or inoperative position, andthe star wheel H5 is free to turn with Shaft 2s independently 7' of theeccentric member and other parts associated therewith. At this time, thespring |01 is under tension and tends to move the ring in a clockwisedirection, as viewed from above. In Figure 4, the shoe operating shaft84 has been rocked in a counter-clockwise direction, as considered inFigure 2, into its extreme position, the

eccentric member being at this time disposed in its extreme position tothe right of shaft 28 and being on dead center with this shaft and pin8|. This provides an eccentric lock which serves effectively to hold theshaft 84 in rocked adjustment.

When it is desired to rock the shaft in the other direction, finger I |9is raised into inoperative position. Spring |01 then turns the ring soas to bring the tabs ||4 into contact with the other ends of the notches||3, the spring then acting to turn both the ring and the clutch yoke I2in a clockwise direction as viewed in Figure 4. This movement of yoke||2 moves the disc 8 inward into engagement with star wheel I5 and, theshaft 28 being driven, clutches the eccentric member to the star wheelfor rotation therewith. This movement of the yoke ||2 serves first tomove the disc ||8 inward, after which the reduced portion ||2b of recess||2a is brought into position to fit about the outer portion of disc I8thus holding it in its inner or operative position.l 'I'he eccentricmember turns with the star wheel through a half rotation, at which timethe other tab ||4 of ring ||2 contacts trip finger ||9, it beingunderstood that this trip nger is returned to its operative position byspring |23 immediately upon release of rod |2|. Upon contact of the tab||4 with the trip finger, ring is held against turning movement, yoke 2continuing to turn with the star wheel vuntil the end walls of notches!|3 contact the tabs, at which time the yoke also is held againstturning movement. Upon continued turning of the star wheel and theeccentric member, slot ||1 is again brought into alignment with recess|2a, atwhich time disc |18 is forced outward into this recess, by thepressure exerted upon this disc by the star wheel. This returns theparts to their relative positions of Figure 4, except that the disc 8andv asso-l ciated parts will have been moved through an arc of 180 fromthe positions of this figure, and the eccentric element will have beenturned through an arc of 180, at which time the shoe operating shaft|84v has been rocked into its extreme position in a clockwise directionas considered in Figure 2. At this time, the eccentric element is againon dead center with the shaft 28 and pin 8 l, providing an effectivelocking means for holding shaft 84 in its rocked position.

An arm |25 (Figure 1) is suitably secured, as by means of a pin |26,upon shaft 84 adjacent the holding member 86. This arm extends upwardfrom the shaft and is bifurcated atits upper end for reception of areduced neck (Figure 10) |21 extending rearward from a head |28 which issecured upon the forward end of an adjusting rod |29. Neck |21 abuts ahead |30 at the forward end of a thimble |3|, which is also mountedupo'n the rod |29. 'I'his thimble screws through a cruciform member |32rockably mounted in a shoe carrying arm |33. This arm is bifurcated atits lower end, which straddles arm |25, and is loosely mounted uponshaft 84. At its upper end arm |33 is suitably pivoted to a shoe |34which cooperates with the ironing roll. This shoe has a concaved forwardface to fit above the roll, when the shoe is in its forward position,and is provided with suitable heating means, preferably electrical meanswhich may be controlled by the same switch which controls the motor. 5

Rod |29 has a pin and slot connection to thimble |3| for rotating thelatter while being slidable therethrough. A knob |35 is suitably securedupon rod |29 at the outer end thereof for rotating the rod in desireddirection. The forward 10 face of this'knob is recessed and receives oneend of an expansion coil spring |36, the other end of which seats in acup washer |31 mounted about the rod and abutting the rearward end ofthimble 3|. The means for coupling the arms 15 |25 and |33 together isthe -same as that disclosed in my above identified Patent No. 1,867,839,and need not be described here in greater detail.

With the arms |25 and |33 coupled together, 2o when shaft 84 is rockedin a counter-clockwise direction, as viewed in Figure 2, arm |25 acts.through head |28 and rod |29 and associated parts to swing the shoesupporting arm |33 forward thus bringing the shoe into contact with 25the roll or the work thereon. After this occurs arm |25 moves forward ashort distance, placing spring |36 under compression so that the shoe isheld to the roll by spring pressure. By rotating rod |29 the effectivespring pressure 30 exerted on the shoe can be regulated as required.

A release lever 40 is connected to member |32 for rocking the same tocouple and uncouple the arms |25 and 33. This lever is provided, at itslower end, with a finger 4| which passes through 35 the upper arm ofmember |32, this finger being disposed at right angle to the lever. n

' Arm |32a of member |32 and through which finger |4| passes, isprovided with two notches |42 and |43 extending from the opening which4o receives finger |4|, these notches being at the rear face of arm|32a. An expansion coil spring |44 is mounted about finger |4| andconfined betwe'en the forward face of arm |32a and an abutment in theform of a washer |45 suitably secured 45 upon lfinger |4| at the forwardend thereof. This spring urges lever I 4| toward arm |32a so as to holdit in one or the other of the notches |42 and |43. When lever |40 is innotch |42 it is disposed in vertical position and projects well abovethe shoe |34 and the roll 65. A knob |46 is provided at the upper end oflever |40 for convenience in grasping the same and, in the verticalposition of the lever, this knob is disposed a suiiicient distance abovethe hot shoe so as to be readily grasped by the operator from in frontof the machine without danger of the operators arm or hand coming intocontact with the hot shoe. The considerable length of lever |40 is alsoof advantage in facilitating operation 60 of the coupling means. Whenthe lever |40 is disposed in the notch |43 it is at an angle ofapproximately 45 to the horizontal so that knob |46`is below the top ofshoe |34, and this shoe and the roll may be enclosed by a box cover |4165 seating upon the bed plate I5 with the top wall of this coveradjacent the top of the shoe and the roll. I

When the machine is being used for ironing, the lever |20 occupies thevertical position shown 70 in dotted lines in Figure 1. By swinging thislever rearward, member |32 is rocked so as to disengage head |28 andneck |21 from arm |25 and swing head 28 upward and rearward into contactwith arm |33, thus swinging this latter acarrea element 86a formedintegrally with the holding' member 86 and projecting into the path ofmovement of arm |33. In order to couple the two arms together, lever |40is swung forward. In the forward movement of this lever head |28contacts the forward face of the upper end of arm |25and neck |21 passesinto the slotted end thereof, coupling the arms together.

In the normal operation of the machine," cam member 99 is turned to itsinoperative position illustrated in Figure 3 thus permitting of verticalmovement of fork member 9| in either direction. When the shoe is in itsopen or inoperative position, pin 89 contacts the wall at the upper endof slot 90 so-as to hold arm 81 in raised position, thus holding clutchmember 49 in its raised or inoperative position against the tension of,apringI 'I'he shafts 28 and 39 are then declgitched so that the roll isnot rotated when the "shoe is out of operative relation thereto. Uponmovement of the shoe into operative relation to the roll, shaft 84 isrocked in a counterclockwise direction, as considered in Figure 2, andspring 46 acts to move clutch member 49 downward into engagement withclutch member 36, at which time arm 81 occupies the position illustratedin Figure 2. Accordingly, when the shoe is moved into' operativerelation tol the roll, the shafts 28 and 39 are coupled together todrive the roll 65, in the normal operation of the machine. With the shoein operative relation to the roll, clutch member 49 may be raised intoinoperative position,y by turning the clutch control handle |02 inproper direction, at the pleasure of the operator. This permits ofmomentary stopping of the roll so as to assure thorough drying ofrelatively damp portion of the article being ironed, in the mannerpreviously described. Also, by retaining the clutch member 49 in itsraised or inoperative position, the shoe may be moved toward and awayfrom the roll while the latter remains stationary, by proper operationof the rod I2 for pressing suits and like articles. It will thus beobserved that under normal conditions the roll 65 is driven when theshoe is in operative relation to the roll, but rotation of the roll maybe prevented at the will of the operator and as conditions require.

The box .cover |41. may be constructed and mounted as in my Patent No.1,867,839, or as in the Anderson and Janda patent, above-identi ed, andthe clutch mechanism for controlling operation of the shoe and the meansfor coupling the shoe supporting arm to the arm which is secured uponthe shoe operating shaft are similar to the corresponding meansdisclosed in my above identified patent and need not be furtherillustrated nor described here, it suflicing to note that suitable meansis provided for operating the shoe shaft 84 and suitable means isprovided for establishing operating connection between -this shaft andthe shoe.
